4WE6J6X/EG24N9K73L/B10SO407

The 4WE6J6X/EG24N9K73L/B10SO407 valve is manufactured by Bosch Rexroth within the WE Directional Spool Valves series. It directs pressurized oil to selected actuator ports in hydraulic automation where compact electrical actuation is required. The size 6 body provides passage dimensions suited to medium flow rates without imposing excessive pressure loss. A J-coded spool establishes predefined flow paths that shift the circuit between neutral and working positions. Electrical control is supplied by a 24 V DC coil, and the ±10 percent voltage tolerance allows operation on supplies that may fluctuate within typical industrial limits. The solenoids draw 8 W when energized, minimizing heat generation and permitting dense manifold layouts. Continuous energization is permitted because the coil is rated for a 100 percent duty cycle, so command signals can be held as long as machine logic demands. Switching may occur up to two times per second under SO407 parameters, supporting rapid cycling, while a concealed manual override lets maintenance staff reposition the spool without disturbing electrical wiring.

This valve mounts on subplates that follow the ISO 4401-03-02-0-05 interface, so it can replace standard D03 components without modification, and the NFPA D03 porting pattern ensures alignment of pressure and work ports across international installations. The working ports P, A, and B withstand operating pressures up to 315 bar, enabling use on presses and mobile equipment that run at high system pressure, whereas the tank port is limited to 210 bar, protecting return-line seals against overload. When fully shifted, the flow channel accommodates up to 60 liters per minute, which matches the passage size and keeps velocity within recommended limits. A 1.0 mm throttle orifice is built into port P to damp pressure surges when the spool transitions. Circuit cleanliness must be maintained to ISO 4406 class 20/18/15 or better to prevent contamination from sticking the precision-ground lands. The assembled unit with two solenoids weighs 1.95 kg, allowing technicians to install it single-handed on compact manifold stations.
